ترجیحات خانوار برای اقدامات صرفه جویی در انرژی: روش انتخاب مدل های گسسته

The aim of this paper is crystallized around the research of the energy saving measures adoption's determinants in the residential sector. Using data from the latest survey of the Tunisian Company of Electricity and Gas, we study the specifications of discrete choice models to the characteristics of three different electrical purposes: the Solar Water Heaters, the Low-Energy Bulbs and the classes of energy efficient refrigerators. The results suggest the strong heterogeneity of households, making the effect of energy policies a bit obvious. However, by adopting a perfect rationality, these households give importance to the enrichment of electricity prices and gains in energy savings, as far as the importance of the changes in equipments’ price. Subsequently, we urge policy makers to create mechanisms of balancing the grants of conventional energies by increasing the grants on energy efficient equipments’ purchasing prices.
